Melting / freezing point
- Key result
- Melting / freezing pt.:
- >= -39 - <= 60 °C
- Atm. press.:
- ca. 1 013 hPa
Any other information on results incl. tables
The test item shows a melting area of crystalline subcomponents between -39 °C and 60 °C according to the definition in the OECD Guideline 102 (mean value from repeat determination).
-39 °C to 60 °C (from first measurement)
-40 °C to 60 °C (from second measurement)
-39 °C to 60 °C (from third measurement)
The cooling runs shows a beginn of crystallization at ca. 52 °C. Additionally the heating runs show a glass transition temperature at -49 °C (1st heating run). In the 2nd heating run the test item shows a melting although.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
